Batteries

i need help. i have paired up 2 7.2v 4300mAh NiMH battery packs to give me 14.4v. on my Pro-Peak Constellation Charger what should i set it to for charging them? Cheers

never used the above charger but mine you just set what rate you want to charge at max 12 cells though

12 cells at 4300mAh charge at 3 amps max, start off less if in doubt.

Cheers guys. The main prob i was having was it saying output voltage too low. i had it set how Ed said. Had a some advive through msn telling me to check my batts with multimeter so ill do that in the morning and then ill give you an update.
Thanks

Are you sure it was output voltage and not input. Are you running off a power supply or battery?

it was input. and im running off a power supply.

Input voltage needs to be about 13V

Heya guys. Got a question.
I work at a company which supplies batteries and they have this product.

I was thinking of getting a few and making a pack as I can get them at a low price. Would this just be silly? How can I check to see how much these can dump? They wont have to dump massive amounts. 4 Drills and a linear actuator.

Im afraid that these wont cut the cheese for us.

not good aye? Oh well guess there are no cheap shortcuts.

generally with things like batteries the cheap options are cheap for a reason :)

I know as I just bought some A123s *starts counting the leftover pennies*
